BF 37 8 OHM

Overview

The Visaton BF 37 is a full-range speaker with a diameter of 3.2 cm (1.3 inches). It features an 8-ohm nominal impedance and operates within a frequency range of 220 Hz to 20,000 Hz. The unit has a power handling capacity of 5 watts and utilizes a neodymium magnet structure.

Feature Summary

• Compact full-range design suitable for space-constrained audio applications
• Neodymium magnet construction for high efficiency in small form factors

Applications

• Miniature audio devices
• Small enclosure loudspeaker systems
• Replacement drivers for compact electronics

Procurement Notes

Verify the specific impedance rating matches the target circuit requirements. Confirm that the physical dimensions are compatible with the intended mounting location. Ensure the power handling capabilities align with the expected signal levels to prevent damage during operation.

Selection Notes

Select this component when a small footprint is required alongside adequate midrange performance. Consider the limited low-frequency extension below 220 Hz when designing the acoustic enclosure. Evaluate the magnetic structure benefits against cost constraints for mass production.

Part Context

This model belongs to the Visaton BF series, which focuses on miniaturized audio solutions. The series typically employs neodymium magnets to maximize output while minimizing size. These speakers are engineered for integration into portable or embedded audio hardware where standard drivers cannot fit.

Replacement Considerations

Check for alternative Visaton models with similar diameter and impedance if stock is unavailable. Verify that any substitute maintains comparable frequency response characteristics to preserve audio quality.
